[0034] The following will be combined with Figures 1-11 Describe the fan tower barrel system of the present utility model.

[0035] As Figures 1 to 11As shown in the figure, the fan tower barrel system includes a tower barrel, a cable guide frame 20 and a docking platform 30. A guiding device 40 is installed inside the tower barrel, and the elevator 100 can move up and down along the guiding device 40. The cable guide frame 20 is slidably installed on the guiding device 40, and the docking platform 30 is fixed inside the tower barrel; the cable guide frame 20 is provided with a cable through hole 21 for the cable to pass through. When the elevator 100 moves above the docking platform 30, the cable guide frame 20 can move along the guiding device 40 together with the elevator 100; when the elevator 100 moves below the docking platform 30, the cable guide frame 20 is placed on the docking platform 30.

[0036] As Figures 1 to 8 shown, for the ladder-guided elevator, the guiding device 40 is a ladder 41. As Figures 9 to 11 shown, for the wire rope-guided elevator, the guiding device 40 is a guiding wire rope 42. The elevator 100 can move up and down along the guiding device 40. As Figure 3 、 Figure 8 and Figure 10 shown, the cable guide frame 20 is provided with two cable through holes 21, one of the cable through holes 21 is for the traction wire rope 110 to pass through, and the other cable through hole 21 is for the safety wire rope 120 to pass through. It can be understood that the two cable through holes 21 are arranged at intervals, and the interval is equivalent to the interval between the traction wire rope 110 and the safety wire rope 120. Optionally, the aperture of the cable through hole 21 is larger than the diameter of the cable, and the cable can shake slightly in the cable through hole 21 to avoid the cable through hole 21 overly restricting the cable.

[0037] For the ladder-guided elevator, as Figures 1 to 5 shown, the docking platform 30 can be directly fixed to the ladder 41. Or, the docking platform 30 is fixed to the inner wall of the tower barrel through a support member. Or, as Figures 6 to 8 shown, the docking platform 30 is fixed to the working platform 11 inside the tower barrel. For the wire rope-guided elevator, the docking platform 30 is fixed to the inner wall of the tower barrel through a support member; or, as Figures 9 to 11 shown, the docking platform 30 is fixed to the working platform 11 inside the tower barrel. As long as when the elevator 100 is below the docking platform 30, the docking platform 30 can support the cable guide frame 20 and limit the moving position of the cable guide frame 20 to achieve the docking of the cable guide frame 20. It can be understood that the docking platform 30 does not prevent the up and down movement of the elevator 100, and only abuts against the cable guide frame 20 to restrict the downward movement of the cable guide frame 20. The docking platform 30 is fixed by welding or screwing, and the present invention embodiment does not specifically limit the fixing method of the docking platform 30.

[0038] For the ladder-guided elevator, as Figures 1 to 8As shown, the cable guide frame 20 is in the shape of an annular square or a flat plate. One side frame is slidably engaged with the ladder 41 through a guide wheel 51, and the other side frame is provided with a cable through-hole 21 for the safety wire rope 120 and the traction wire rope 110 to pass through. For the wire rope guided elevator, as Figures 9 to 11 shown, the cable guide frame 20 is in the shape of a strip plate. Both ends thereof are slidably engaged with the guide wire rope 42 through guide wheels 51, and a cable through-hole 21 is provided in the middle for the safety wire rope 120 and the traction wire rope 110 to pass through.

[0039] During the lifting process of the elevator 100, the safety wire rope 120 and the traction wire rope 110 may be entangled due to a large swing amplitude. As the elevator 100 rises, the cable guide frame 20 moves with the elevator 100 at the top of the elevator 100, and the cable through-hole 21 on the cable guide frame 20 is used to prevent the safety wire rope 120 and the traction wire rope 110 from being entangled, improving the running smoothness. When the elevator 100 descends, the cable guide frame 20 moves downward along the guiding device 40 under the action of gravity. When the elevator 100 runs below the docking station 30, the cable guide frame 20 is placed on the docking station 30 and stops moving, and the cable guide frame 20 is constrained by the docking station 30 to stay at the docking station 30. When the elevator 100 rises above the docking station 30 again, the cable guide frame 20 rises with the elevator 100 to prevent the safety wire rope 120 and the traction wire rope 110 from being entangled.

[0040] In the fan tower barrel system provided by the embodiment of the present utility model, the docking station 30 is arranged inside the tower barrel, the cable guide frame 20 is placed on the docking station 30 and can slide along the guiding device 40. When the elevator 100 moves upward, the cable guide frame 20 moves synchronously and the cable through-hole 21 provided thereon is used to prevent the traction wire rope 110 and the safety wire rope 120 from being entangled, ensuring the normal operation of the elevator 100. When the elevator 100 moves below the docking station 30, the cable guide frame 20 is placed on the docking station 30 and cannot move further, realizing the docking of the cable guide frame 20, and the structure is simple.

[0041] In a specific embodiment, as Figures 1 to 8 shown, the guiding device 40 is a ladder 41, the cable guide frame 20 is installed on the ladder 41 through a guide wheel 51, and the docking station 30 is fixed to the ladder 41 or the working platform 11 inside the tower barrel.

[0042] As Figures 1 to 8As shown, the cable guide frame 20 is in a square shape and includes a first side frame 201, a second side frame 202, a third side frame 203, and a fourth side frame 204. The first side frame 201, the second side frame 202, the third side frame 203, and the fourth side frame 204 enclose to form a square frame. Among them, the second side frame 202 and the fourth side frame 204 are opposite to each other and the same-side ends of the two are exposed outside the third side frame 203. The third side frame 203 is closer to the ladder 41 than the first side frame 201. The cable through hole 21 is provided on the first side frame 201. The guide wheels 51 are installed on the parts of the second side frame 202 and the fourth side frame 204 that are exposed outside the third side frame 203 and are located on the opposite sides of the second side frame 202 and the fourth side frame 204. Thus, when the guide wheels 51 move along the ladder 41, the second side frame 202 and the fourth side frame 204 are located outside the ladder 41 and will not be interfered by the ladder 41.

[0043] Specifically, the guide wheels 51 are arranged in pairs. Each pair of guide wheels 51 is rotatably installed on the cable guide frame 20 and is clamped on the vertical rods of the ladder 41. As Figure 1 and Figure 4 shown, on the side of the second side frame 202 facing the fourth side frame 204 and on the side of the fourth side frame 204 facing the second side frame 202, a pair of guide wheels 51 are respectively provided. The two guide wheels 51 on the second side frame 202 are clamped on one side vertical rod of the ladder 41, and the two guide wheels 51 on the fourth side frame 204 are clamped on the other side vertical rod of the ladder 41, so that the cable guide frame 20 can move upward along the ladder 41. It can be understood that the number of pairs of guide wheels 51 provided on the second side frame 202 and the fourth side frame 204 can also be two pairs, three pairs, etc., to improve the movement smoothness of the cable guide frame 20.

[0044] In addition, the wind turbine tower barrel system further includes a support arm 52 and a support wheel 53. The support arm 52 is fixed to the cable guide frame 20. The support wheel 53 is rotatably installed on the support arm 52 and is in sliding cooperation with the ladder 41.

[0045] As Figure 4 and Figure 5 shown, support arms 52 are installed on the outer sides of both the second side frame 202 and the fourth side frame 204. Optionally, the support arm 52 is a Y-shaped frame or a straight plate. By adding the support arm 52, the connection strength between the cable guide frame 20 and the ladder 41 is improved. One end of the support arm 52 away from the cable guide frame 20 rotatably installs the support wheel 53. The support wheels 53 are arranged in pairs. Each pair of support wheels 53 is clamped on the vertical rod of the ladder 41 to hold the ladder 41 tightly and can move up and down along the ladder 41. Thus, the support wheels 53 and the guide wheels 51 are arranged at intervals up and down, which can improve the sliding smoothness of the cable guide frame 20 along the ladder 41.

[0046] In an optional embodiment, as Figure 4As shown, the docking platform 30 includes a vertical plate 31 and a horizontal plate 32. The vertical plate 31 is perpendicularly fixed to the horizontal plate 32. The vertical plate 31 is fixed to the ladder 41, and the horizontal plate 32 can abut against the cable guiding frame 20.

[0047] As Figures 1 to 5 shown, the docking platform 30 is an L-shaped plate, including a horizontal plate 32 and a vertical plate 31. Among them, the vertical plate 31 is fixed to the ladder 41 through a pressing plate 33. The horizontal plate 32 is located in the gap between the elevator 100 and the ladder 41 and does not interfere with the normal lifting of the elevator 100. Specifically, the cable guiding frame 20 further includes a docking plate 205. The docking plate 205 is fixed to the third side frame 203. The docking plate 205 overlaps the horizontal plate 32 of the docking platform 30 to restrict the position of the cable guiding frame 20.

[0048] In another alternative embodiment, the docking platform 30 is fixed on the working platform 11 inside the tower barrel. The docking platform 30 is provided with positioning posts 34, and the cable guiding frame 20 is provided with positioning holes 22. The positioning posts 34 and the positioning holes 22 are correspondingly arranged. When the docking platform 30 abuts against the cable guiding frame 20, the positioning posts 34 are inserted into the positioning holes 22 to improve the restraint of the docking platform 30 on the cable guiding frame 20.

[0049] As Figures 6 to 8 shown, the surface of the docking platform 30 protrudes with positioning posts 34, and the cable guiding frame 20 is correspondingly provided with positioning holes 22. When the cable guiding frame 20 is erected on the docking platform 30, the positioning posts 34 are inserted into the positioning holes 22. Specifically, two, three or more positioning posts 34 can be provided, and the multiple positioning posts 34 are arranged at intervals. Optionally, the multiple positioning posts 34 are located in the same row, or are arranged in a staggered manner in different rows.

[0050] In a specific embodiment, the guiding device 40 is a guiding wire rope 42. The cable guiding frame 20 is in the shape of a strip plate. The two ends of the cable guiding frame 20 are respectively slidably connected to the corresponding guiding wire ropes 42. The docking platform 30 includes two supporting plates 35, and the two ends of the cable guiding frame 20 can respectively overlap on the corresponding supporting plates 35.

[0051] As Figures 9 to 11 shown, the cable guiding frame 20 is in the shape of a strip plate. The cable through hole 21 is located in the middle of the cable guiding frame 20, and the two ends are respectively slidably matched with a guiding wire rope 42. During the lifting process of the elevator 100, the cable guiding frame 20 is located at the top of the elevator 100 and can move together with the elevator 100. The docking platform 30 is fixed on the working platform 11 inside the tower barrel or is fixed inside the tower barrel through a support frame.

[0052] To make the strip-shaped cable guiding frame 20 erected on the docking platform 30, the docking platform 30 includes two oppositely arranged supporting plates 35, and each supporting plate 35 supports one end of the cable guiding frame 20. As Figure 9 and Figure 10As shown, the pallet 35 is L-shaped. One of the plate bodies extends vertically for fixed connection with the vertical plate on the working platform 11, and the other plate body is horizontally arranged to support the cable guide frame 20.

[0053] At opposite ends of the cable guide frame 20, pairs of guide wheels 51 are respectively provided. Each pair of guide wheels 51 cooperates with each other to clamp the guide steel wire rope 42.

[0054] The guide wheels 51 are rotatably installed at the ends of the cable guide frame 20. Two guide wheels 51 are arranged at the first end of the cable guide frame 20, and a channel for clamping the guide steel wire rope 42 is formed between the two guide wheels 51. Similarly, two guide wheels 51 are arranged at the second end of the cable guide frame 20, and a channel for clamping the other guide steel wire rope 42 is formed between the two guide wheels 51.

[0055] To improve the stability of the sliding fit between the cable guide frame 20 and the guide steel wire rope 42, multiple pairs of guide wheels 51 can be arranged at the ends of the cable guide frame 20. For example, an extension plate is fixedly installed at the end of the cable guide frame 20, and multiple pairs of guide wheels 51 are installed on the extension plate, with the extension plate providing sufficient installation space for the multiple pairs of guide wheels 51. Optionally, the bottom surface of the extension plate is flush with the bottom surface of the cable guide frame 20, and the top surface of the extension plate is higher than the top surface of the cable guide frame 20, so as to ensure the stability of abutting against the top surface of the docking station 30 while providing sufficient installation space for the guide wheels 51. Of course, the bottom surface of the extension plate can also protrude outward from the bottom surface of the cable guide frame 20, and the docking station 30 is provided with an avoidance through hole corresponding to the extension plate.

[0056] As Figures 9 to 11 shown, the pallet 35 is provided with an avoidance hole 37 for avoiding the guide wheels 51. When the bottom surface of the cable guide frame 20 is placed on the surface of the pallet 35, part of the guide wheels 51 is accommodated in the avoidance hole 37. By providing the avoidance hole 37, the size of the guide wheels 51 is not restricted by the thickness of the cable guide frame 20, so that larger-sized guide wheels 51 can be selected to improve the stability of the sliding fit with the guide steel wire rope 42. It should be noted that the avoidance hole 37 can be in the shape of a groove or a through hole, as long as it can play the corresponding role. The present invention does not specifically limit the specific form of the avoidance hole 37.

[0057] When the elevator 100 drives the cable guide frame 20 at the top to move upward, the guide wheels 51 move along the guide steel wire rope 42. When the elevator 100 moves downward, the cable guide frame 20 moves downward under the action of gravity until the cable guide frame 20 is blocked by the docking station 30 and is placed and stays at the docking station 30.

[0058] Optionally, as Figure 11 shown, the pallet 35 has a guide inclined surface 36.

[0059] AsFigure 11 As shown, the pallet 35 includes a bottom plate and inclined plates provided on opposite sides of the bottom plate. The inclined plates form an obtuse angle with the bottom plate, and the two inclined plates are in a V shape. When the cable guide frame 20 moves downward to overlap with the pallet 35, the surface of the inclined plate serves as a guiding inclined surface 36 to guide the cable guide frame 20 to overlap on the bottom plate.

[0060] An embodiment of the present invention further provides a wind power generation set, which includes a wind turbine and the above-mentioned wind turbine tower system. The wind turbine is installed on the tower barrel.

[0061] The wind power generation set further includes a lift 100, and the lift 100 is slidably installed on the guiding device 40. When the guiding device 40 is a ladder 41, the lift 100 is slidably engaged with the ladder 41 through rollers and can be lifted and lowered along the ladder 41 under the action of a driving mechanism. When the guiding device 40 is a guiding wire rope 42, guiding blocks are respectively provided on both sides of the lift 100, and the guiding wire rope 42 passes through between a pair of wheel bodies installed on the guiding blocks.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
